What a flood zone means for a Charles Mix County buyer
Here's why the zone matters at a closing in Wagner. When a structure near Lake Andes is mapped in a high-risk zone and secures a loan from a federally regulated or insured lender, a flood policy becomes a loan condition; that applies where the local government around Lake Andes is in the National Flood Insurance Program. In Zone X near Wagner, federal rules do not require a policy; pricing a policy for land near Lake Andes is still worth a call. Where a structure near Wagner looks higher than the shading suggests, FEMA's LOMA process allows a review; a surveyor near Lake Andes can supply the elevation data. Placing fill on low ground near Wagner frequently requires a permit and an elevation check, and the building office serving Lake Andes explains the steps.
